Specification of Letters Patent.

Patented A11 10, 1915 Application filed October 10, 1910i Serial No. 586,416.

To all whom. it ma /ronccrn.'

Be it known that I, ALPHEUs FAY, a citizen of the United States, residing at Louisville. in the county of Jefferson and State of Kentucky, have invented a crtain new and useful Mechanical Movement, of which the following is a. specification.

My invention relates to machine elements, and has for its object the utilization of the reaction incident to differential power transmi on mechanism. whereby the efficiency of said transmission mechanism is raised, and whereby the etliciency is maintained uniform at all ratios of change-0f speed.

My invention consists in the combination with the driving member and the driven member and operative connect-ion therebe tween, ofmean's for utilizing the reaction of said connection, as will hereinafter be more full, described and claime l.

1n the drawings: Figure 1 illustrates a simple embodiment of my invention, wherein the reaction is utilized to assist in the driving of the driven member by acting directly thereon. Fig. I? is a similar illustration of the device in which the reaction is utilized to act directly upon the driving member and thereby assist in driving the driven member. Fig. 3 illustrates a modification in which the intermediate shaft on which the reaction is utilized becomes the shaft with which the work is performed. Fig. 4 illustrates a device in which the reacting either directly upon the driving shaft or directly upon the driven shaft, and also by means of which the ratio botwc n the speed of the driving shaft and that of the driven shaft may be changed.

Fig. 5 illustrates my invention applied to a grinding machine adapted to be driven by hand. Fig. 6 illustrates the application of my invention to a lathe, with means for obtaining various changes of speed thereon.

Fig. 7 illustrates the vention to an upright struction, adapted to and having means in drill of heavy conbe operated by power, conjunction therewith for reversing the direction of rotation of the spindle. Fig. 8 illustrates the application of my invention to an upright drill of lighter ci'aistruction, adapted to. be driven by hand,

and having an automatic feeding device opapplication of my incrating in COHjUI ICtlOD therewith. Fig. 9 illustrates the application of my invention to a mowing machine, with provision for changing the speed at which the cutter-bar is operated. Fig. 10 is a sectional plan View of a lawn mower with my invention applied thereto, the driving being effected through the wheel on one side only, the section being taken on the line 2 of Fig. 11. Fig. 11 is a vertical cross section on the line :1=;1rof Fig. 10. Fig. 12 is a detail view of the driving gear in the lawn mower. Fig. 13 is a sectional plan view of a lawn mower with my invention applied thereto, the driving being effected through both wheels thereof. Fig. l-l illustrates the application of my invention to a centrifugal blower to be operated by hand. Fig. 15 illustrates the application of my invention to a cream separator, the part of the machine in which my invention is embodied being shown in vertical cross section, while the remainder of the machine'is shown in front elevation. Fig. is an enlarged detail sectional view of the ballbem'ings for the vertical shafts in the cream separator. Fig. 17 is a side elevation of a motor boat equipped with my invention as a means for driving the propeller. Fig. 18 is a vertical longitudinal section of the part of the boat containing my invention. Fig. 19 is a vertical longitudinal section of a device illustrating theapplication of my invention to a dynamo electric machine, whereby the machine may be driven at a high speed by an engine or other motive apparatus operating at a lower speed, provision being made for changing the speeds thereof.

The principle of my invention may be understood by reference to Figs. 1 and 2 of the. drawings. In Fig. l the driving shaft 1 and the driven shaft L). are in alinement. The driven shaft 2 has a bearing 2, while the driving shaft 1 has a bearing 1, and also has a reduced portion 1 bearing in a central opening 2 in the driven shaft 2. The driving gear L3 is keyed on the driving shaft 1, and the reactive gear 3 is keyed on the driven shaft 2, these two gears being adjacent to each other. The reactive gear 3 carries the stepped gear l," mounted on a stud therein, said stud being parallel to the driving shaft .1 and the driven shaft 2, so that the stepped gea'n 4 is planetary with respect to said shafts. The smaller member 4 of the gear 4 is in mesh with the driving gear 2. The stepped gear 5 is loosely mounted on the driving shaft 1, adjacent to the hearing 1, and it has a smaller member 5 in mesh with the larger member 4 of the gear 4, that is carried on the reactive gear 3. These members 4" and 5 are of equal diameter, while the member 4 of the stepped gear carried on the reactive member is of less diameter than the driving gear 2, in such driven'shaft or the intermediate shaft.

proportion as may be desired. An interme-' diate shaft .6 is journaled in bearings 6 and carries a gear 6 rigidly mounted thereon, Whichis in mesh with the larger member 5 of the gear 5, that is loosely mounted on the driving shaft 1. This intermediate shaft 6 also has a pinion 6 rigidly mounted thereon, and this pinion is in mesh with the reactive gear 3 that is rigidly mounted on the driven shaft 2. As shown, the driven shaft has a reduced portion 2, to Which any form of operative member may be attached for performing work while the intermediate shaft 6 also has a similar reduced portio 6 for the same purpose, and work may be performed either with the driven shaft-4 or with the intermediate shaft'ti. In either instance the reaction on the gearing incident to the causing of a difference of speed between the driven shaft and the driving shaft will be utilized to virtually assist the motive apparatus employed, thereby providing a balanced action. Fhis dispenses with stationary reaction, and I have found, in practice, that this reduces the energy necessary to perform the work with either tli; the Worlrbe done with the driven shaft, the action Will-take place through the driving gear 2, the gears 4 and 5 and 'thr'ough the' gear 6"? and pinion 6 and the'intermediate-- shaft 6 on which they are mounted, through the reactive member 3 and onto the driven shaft 2; at the same time any reaction will operate directly through the reactivememher 3 onto the driven shaft 2. With this arrangement the teeth of the pinion 6 ;will be hearing forward against the teeth of the reactive gear 3, and the action and'reaction willcoact to perform the work imposedon the driven shaft 2. If the Work "be per-' formed with the intermediate shaft 6, the action will take place from the driving gear 2 to the intermediate shaft 6, while the reaction will be transmitted from the driving gear 2 through the member.4- *-of the gear 4 onto the stud 4 to the reactive gear 3,; and from, there through the pinion 6 onto the intermediate shaft 6. In this instance the teeth of the reactive gearB will bear forward against the teeth of the pinion 6 on the intermediate shaft 6.

Arranged as illustrated in- Fig. 2, the driving shaft 1 and the driven shaft 2 have their bearings 1 and 2 respectively, and the The driving gear 2 meshes with the memher 4 on the gear 4, but the'member 4' of said gear 4 meshes with the driven gear 7 rigidly mounted on the driven shaft 2. The stepped gear 5 is replaced by; a simple gear 5 rigidly mounted on the d'riying shaft, and this gear meshes with the gear 6 that has a pinion 6 to rotate therewith loosely on the intermediate shaft 6, which is stationarily mounted as shown.

The pinion 6" meshes with the reactive gear 3. 'In thiscase Work is done only with the driveiisha-ft 2, it being provided with the reduced portion 2 as before, described. When work is performed with this driven shaft by the rotation of the driving shaft 1, the action takes place through the driving gear 2 and the gear 4 onto the driven gear? and onto the driven shaft 2. The reaction takes place from the driving gear 2 onto the smaller member 4 of the gear 4, and through the stud 4 to the reactive gear 3, and from there through the pinion 6 vand the gear,6' turning together in the intermediate shaft 6, and through the gear 5 back to the driving shaft 1. In this instance the teeth of the gear 6*" on the intermediate shaft 6 will press forward against the teeth of the gear 5 on'the driving shaft 1, and through the assistance of the reaction thus transmitted to the driving shaft, the torque necessary on the driving shaft to perform a given amount of Work with the'driven shaft will be so modified that the efliciency of thezmachine will remain constant, notwithstanding the increased speed at which the driven shaft is tively. The driving shaft 11 has a reduced portion 11 hearing in a central opening 12" in the driven shaft 12, and both shafts have a common bearing ll which forms part of the reactive member 13', which here takes the form of a 'drumQ-bearing at one end on the driving shaft" 11 adjacent to the bearing 11" and at the other end bearing on the driven shaft 12. This reactive member or drum 13 carries stepped gears 14 and 14 turning loosely on reactive shafts 14' and ed in the. drum l3 pai'allelize and at equal distances radially from the eommonqenter line of the driving she-Ft 11 and driven 14" respectively, which are rigidly xnountith . meshes, and the member is or larger diameter than the member 14" with which it meshes. The members ll and 15 mesh- W r are of mind diameter, as are the member il and the driven gear 1 .5, wh, i mesh together. It will thus be seen that a t n oi gears is provided inside the drini the dr. 111g gear 12 to the driven gear 16, constituting an operative connention between. the driving shaft- 11 and the driven shaft- 12. the reaction of which imposed upon the reactive member '13. and by means of which part of the rotary hmvemeni obtainial from the driving shaft ll will be imparted to the driven shaft 12 and part of said movement imparted to .e reaeti member or drain 13. A. bevel pinion l2" :s rigidly mounted on the driven "'t .13 oi tsido the drum it and a larger r nioa l3 is rigidly mounted on the (lllilll 1 outside thereof adjacent to the bevel p nion ii. The intermediate shaft, 17 carries a larger bevel gear ll in mesh. with the larger bevel pinion ill on drum 13 and this intern; mediate shaltalso carries a smaller bevel gear I?" in'niesh with the smaller pinion 12 on the t ving shaft 1'2. Both. gears are ri idly nicanttal on. said intermediate shaft 17. and the shaft has bearings 17. which, with the hearing ll and the bearing 12 may be rigidly attarhcd together by a snitable l raine With this arrangement,

when the driven shaft rotates, the action \\'Ill take plat-e through the train ol' gears from ist? driving gear 12 to the driven gear 17. and

through the driven shaft l2 and the, a r l?" on the in draft and -from. there to said inl alt. while the reaction will a numb the drain i under the )ped SIJU'S carried thereby. .inion l l thereon. to the bevel no internnaliate shaft 17, and tr said intermediate ,isha'l'l and 7 5e 1;l be performed by the intershait ll 1 above three examples the advantage attained consists in the utilization of the reac am incident to the change of speed from the driving member to the driven memher to virtually assistthe driving member in driving the driven member, and reduce the loss of energy visually involved in performing the work at such speed, so that the elliciency of operation may remain more constant at all speeds and under all conditions.

It. will be understood that no energy is gained, contrary to the law of conservation of energy; but all of the energy applied in driving is transmitted in thet'orm of kinetic energy to the driven element. expended against the foundation fastenings of the machine when afstationarv reactive element is used, is here transmitted to the work and the exertion upon the fastenings of the machine is reduced to that trans mitted thereto due to the friction in the bearings of the 1nachinca negligible quantity in any machine with well designed bean ings. In any machine where the work must be done at a considerably higher speed than that at which the driving force is applied, the loss in the form of potential energy, with a stationary reactive element, is of high percentage. As the ratio of speed increase from driving to driven element rises, the percentage of loss of energy expended potentially on a stationary reactive element increases far faster than does the increase in speed ratio. 1 dispense with this potential energy loss with the result that the work done is directly proportional to the energy expended at, any ratio of speed in crease from driving to driven element, instead of indirectly and varyingly proportional as with a stationary reactiveelement. The unavoidable frictioin of course, is present; but this factor remains the same in either case, and has no bearing on the com- )arison of my invention with the commonly Used principles of machine design. It is with the avoidance of energy loss from high ratios of speed increase from driving to driven element that my invention is directly concerned.

A more elaborate construct-ion permitting ot'a high increase in speed of the driven shalt over that ol' the driving shaft, and allowing of several changes in the speed, illustrated in Fig. l, in which the driven shaft 31 has a bearing 2i at one end, and has a lmaring ii at the other end inside the driving sha't 22 which has a bearing 92'. The reactive member or drum 23 has a hearing at one. end of the driving shalt i l and at the other end and on the drivenshatt 2'2. and carries a series all stepped gears "H and 24 on one siihx and a ser s of similar gears 24: and 21 on the other side loosely mounted on. shafts 2i" and Ji respectively. which are rigidly mounted in said drum and are parallel to the driving shaft and driven shaft and equally spaced radially from the center line thereof The driving gearZl and a series of stepped gears 25, 25 and 25,

The force intermeshed with the similar gears on the shafts 24" and 24" in such a manner as to form a train of gears from the driving gear 21 to the driven gear 22, WhlOh 1s 1ntegral with the driven shaft 22 around the driving shaft 21, and which meshes with the larger member on the last stepped gear 24. This driving shaft 22 is also provided with a set screw 26 so that it may-be tightened upon the driving shaft 21 and driven at the same speed as the driving shaft when desired.

It will be understood when any one of the set screws 26 or the set screw '26 is tightened all the other screws must be loosened. An intermediate shaft 27 is jou-rnaled parallel with the driving shaft and the driven shaft in bearings 27 and the pinion 27 a is rigidly mounted thereon by means of set screws 27'. The reactive member or drum 23 has a gear 23 formed integral therewith ..concentric to the driving shaft-and driven shaft on which the drum rotates, and this gear is in mesh with the pinion 27 on the intermediate shaft 27. Two other gears 27 and 27 are mounted on the intermediate shaft 27-and provided with set" screws 27" and 27 respectively, so that-either of them may be tightened upon the. intermediate shaft to rotate therewith. A gear 21 is mounted on the driving shaft adjacent to the bearing 21 thereof, and provided with a set screw 21" so that it may be tightened.

uponthe driving shaft, and this gear 21 is in mesh with the gear 27 on the intermediate shaft. A gear 22 is mounted on the driven shaft and provided with a set screw 22" so that it may be tightened upon. said driven shaft, and this gear is in mesh with' vthe other gear 27 on the intermediate shaft.

The driven shaft 22 is. provided with a reduced portion 22 upon which a suitable operative member may be mounted to-perform work while the driving shaft 21 has a. pulley 21 by means of which it may be driven by any suitable motive apparatus. I

It will be readily understood that the above described device combines the features of the devices illustrated in Figs. 1 and 2,

allowing the reaction to be utilized either directly upon the driven shaft or upon the be obtained without decreasing-the efficiency with which the machine may be operated renders myinvention specially applicable to all forms of hand driven machines where a high operating speed is desirable, such as the grinding machine illustrated 1n Fig. 5. Here the driving shaft 31 has a bearing 31' near one end and a bearing 31 in the driving shaft 32 at the other end, which driven shaft has a bearing 32. The reactive member or drum 33carries the stepped gears 34 on reactive shafts 34 ,so arranged and designed that the parts balance each other, and three other stepped gears 35 are provided on the driving shaft 31 to intermesh with the various gears 34 and form a train between the driving gear 31 on the driving shaft and the driven gear. 32 that'is integral with the driven shaft 32. A gear 31" is rigidly mounted on the driving shaft 31 along with thedriving gear'31 by means of 1 a cotter 36"taking through sleeves 31*" and 31*" with which said gears are provided, respectively, the driving gear 31 of course being inside the drum 33, while the gear 31 is outside the drum. A tap screw 37 is secured in the frame 38 of the machine and forms a bearing. for anintegrally formed pinion 37" and gear 37 The gear 37 is in mesh with the gear 31 and is of diameter equal therewith, while the pinion 37 is in mesh with the gear 33 that is formed integral with the drum The driving shaft 31 is provided with a suitablehandle 31 and the grinding wheel 32 is mounted on the driven shaft 32 in a well known manner. The frame 38 of the machine is provided with a'clamping device 38*, by means of which it may be secured to a bench or table 39 as is well understood. H

In the lathe illustrated in Fig. 6 the spindle is divided into two parts, so as to comprise the hollow driving shaft 41 and the holiow driven shaft 42. The reactive mem her here consists of two gears 43 spaced apart to allow room. -for the planetary v stepped gears 44 and the stepped gears 45 mounted on the driving shaft 41. The reactive shafts 44 rigidly secure the gesirs 43 together. The various gears 44 and 45 form speed-varying connection between the driving gear 41 and the'driven gear 42 which are adapted to be rigidly secured to the driving shaft 41 and driven shaft 42, respec' tively, by means of set screws 46. The vari-v ous stepped gears 45 on the driving shaft are also detachably secured thereto by set screws 46. so thatby tightening any one of said 'set screws and loosening all the others, different speedvarlations may be obtained between the driving shaft 41 and the driven.

shaft 42., The intermediate shaft 47 carriespinions 47.? rigidly mounted thereon and in mesh with the gears 43 that form the re-.

active member. The gea r. 41 ismounted on the driving shaft 41 and a gear 47 is mounted on the, intermediate shaft- 47 in mesh with the gear 41 and of equal diameter therewith. The gear 42* is mounted on the driven shaft 42 and another gear 47 is mounted on the intermediate shaft 4:? in mesh with the gear i2" and of equal diameter therewith. Any of these gears may be .rigidly secured to its shaft by means of set screws 46". As here shown, the driving shaft 41 hasa pulley 41 by means of which it may be rotated from any suitable motive apparatus, and the driven shaft 42 has a tapered opening to receive a suitable operative member such as the center 42. It will be readily seen that a large numberof different speeds may be obtained on a lathe thus equipped with my invention by merely manipulating the set screws, and all such speeds will be obtained with uniform efficiency.

In the drill illustrated in Fig. 7 the driven shaft 51 has bearings 51 in the column of the drill and also a bearing 51 in the region adjacent to its end. The driven 'shaft here takes the form of a sleeve 52 integral with which is formed the driven gear 52. The readtive member consists in the two gears carrying the two stepped gears 54, on reactive shafts 5%. The. driving gear 51 isoperatively connected, through these gears 54 and the stepped gear 55 mounted on the driving shaft 51, with the driven gear By means of set screws 56 either the driven gear 51 or the gear 55 may be rigidly secured to the driving shaft 51, so that two different speeds may be transmitted to the driven gear 52*. The intermediate shaft 57 has bearings 57 and carries pinions 57 which are in mesh with the reactive gears 53. It also carries a gear 57* and gear 52* is rigidly mounted on the driven shaft or sleeve The gears :32 and 57* mesh together and are of equal diameter. One of the gears 53 has a sleeve 53 surrounding and forming the bearing 51 for the driving shaft 51 and this sleeve 53 carries a bevel gear 53 rigidly secured thereon. The intermediate shaft 57 carries a bevel gear 57 rigidly secured thereon in vertical alinement with the gear 53?. The spindle 58 on the drill has a bevel ge-ar 58 in mesh with the gear 53f below, and a be'vel gear 58 is in mesh with said gear 53 abbve, either of which may be made to impart their rotation received from the bevel gear 53 to said spindle 58 by means of a clutch 59. It will thus be seen that the direction of rotation of the spindle may be reversed without reversing the driving mechanism. Another bevel gear 58, on

said spindle 58, is in mesh with the bevel gear 579011 the intermediate shaft 57, and this gear may also be thrown into engagement with the spindle 58 by-means of the lever 59. The pulleys 51 are mounted on the driving shaft 51 for applying and controlling the application of suitable motive power to the machine. It will be noted that in this instance the speed is reduced from the driving shaft to the spindle 58 and it will be understood that this reduction is accou-iplished with efliciency equal to that attained when the speed is increased.

In the light drill illustratedin Fig. 8 the drivin shaft 1 has a bearing 61 near one end, and has a bearing 61 inside the'driving shaft or sleeve 62 at the other end. The reactive gears 63 carry the stepped gears 64: on reactive shafts 6i and a stepped gear 65 on the driven shaft 61 forms, together with the gear 64, operative connecting means between the driving gear 61 on the driving shaft and the driven gear (3?. which forms part of the driven sleeve 62. By means of set screws (36, either the driving gear 61 or the gear 65 may be rigidly secured to the driving shaft, so that a change of speed may be obtained. The intermediate shaft 67 carries pinions 6'? in mesh with the reactive gears 63. The spindle 68 on the drill is provided with bevel gears 68 and 68 rigidly mounted thereon and a bevel pinion 61 is rigidly mounted on the driven sleeve 62 with the bevel gear 68 in mesh therewith. The bevel gear 68" meshes with the bevel pinion 6'7 rigidly mounted on the intermediate'shaft 67 The dri vingshaft 61' has a suitable handle 61 for driving the machine, and the intermediate shaft 67 is provided with a fiy wheel to regulate the speed thereof. The spindle 68 is fed downward by means of an automatic feed 69 comprising a bracket 69 embracing the l spindle 6S and running on a vertical screw 69 which carries at its upphr end rigidly secured thereto a ratchet wheel69 actuated by a pawl 69 carried on bar 69 that oscillates with a lever 69 that is oscillated by means of a cam 67 rigidly mounted on the intermediate shaft 67. The bar 69 is supported forwardly by means of a link 69. In this instance it will be seen that the action is transmitted from the driving wheel 61 through the train of ears to the driven sleeve 62 and from there through the pinion 61 and gear 68 to the drill spindie 68, while the reaction is transmitted from the gears 64, carried on the reactive member 63, through the intermediate shaft 67 by means of its pinion 67 and its bevel pinion 67 and through the bevel gear 68* to the drill spindle (38, with the advantages hercinbefore mentioned.

In the mowing machine illustrated in Fig. 9 the driving shaft is the axle 71 of the machine and the driven shaft or sleeve 72 turns on this axle 71. The reactive gears 73 carry the stepped gears 74 on reactive shafts 74, and these gears together with the stepped gears 74, which also turn on the axle 71, constitute the speed-varying operative connection between the driving gear 71, which is rigidly secured to the axle 71,

" and of diameten equal therewith.

and the driven gear 72. By means of set screws 76, either the driven gear 71 or the gear 75, adjacent thereto, may be readily secured tothe. axle 71, so that a change of speed may be effected for operating the cutter bars slower or faster in accordance .with

the character of the work to be done. The

intermediate shaft 77 has pinions 7'1 in mesh with the reactive gears 73, and also has a gear 77 rigidly mounted thereon in mesh with and of diameter equal to that of the gear 71 rigidly mounted on the axle 71.

The driven sleeve 72 carries a bevel gear 72*. The connecting shaft 78 of thema chine is journaled at right angles to the axle, and has a bevel gear78 rigidly mounted thereon in mesh with the bevel ear 72 is con necting shaft 78 carries the disk 79 which, through the pitman 79 operates the cutter bar 7 9*. p Y

The lawn mower illustrated in Fig. 10 is similar in construction to the mowing machineQin that the axle 81 thereof is the driving shaft of the mechanism: The driveii shaft is here 'replaced simply by the driven gear 82 and the gear 82 rigidlys'ecured together, and the reactive member takes the form of a shell :83 carrying the stepped gears 84 on reactive studs 84; The stepped gear 85 on the axle 81 completes, with the gears 84, the operative connection between the driving gear 81, rigidly secured to the axle 81 by a cotter 86, and the driven gear, 82. The spindle 87 for'ith e cutting reel 88 carries, rigidly attached thereto, a pinion 87' which is in .mesh with a pinion 87 mounted on a stud 87 and in mesh with a gear 83 formed on the outside of the reactive member 83. Rigidly secured to the pinion 87*,and preferably integral therewith is the gear 87 which is in mesh with the gear 82*." and of diameter equal thereto. It will be seen in this instance that the action and reaction both operate directly upon the intermediateshaft with which the work is performed. v

In the, modification illustrated in Fig. 13,

the various Zparts are simply duplicated, so j is turned by a crankllOl at a speed conthat the butting 'wheel 88 is driven from both sides of the mower, and thevarious parts, being operated in accordance with the illustration contained in Figs. 10 to 12 inclusive, need not be further described.

In the blower illustrated in Fig. 14, the driving shaft 91 has a bearing 91' at one end and a bearing 91"at the other end in the driven shaft 92- which has an opening 92? therefor. The reactive member or drum 93 carries the stepped gears 94 on reactive shafts 94:, and stepped gears 95 turning on the driving shaft 91 complete the operative connection between the driving gear 91% which is keyed to the driving shaft 91, and the driven gear 92 on the driven shaft 92 which is provided with a suitable ball hearing 96, The intermediate stud 97' formsa In the cream separator illustrated in Fig.

15 the driving shaft 101 is vertical and hollow, and thedriven shaft 102 extends therethrough. The driving shaft 101 is support ed on a large ball 101" at its lower "end.

while the driven shaft 7.02 is supported on Ea.

a'vsmallerball 102 within the lower end of the'drivingshaft 101. The drum 103 car' ries the stepped gem-e104 on reactive shafts 104".,'a nd11a series of stepped gears 105 on the driving shaft 101 complete, together with the gears 10%, the operative connection bearing for a gear 97 a in mesh with the gear 93 that is rigidly mounted on a sleeve 03;" 1

between the driving gear 101 and the driven gear 102. The hub of the driving gear 10f is elongated and it is attached to the driving shaft by a long key'106. 'The intermediate stud 107 forms a bearing forthe gear 107 and'the gear 107, integrally formed. The

gear 107 meshes with gear 103 mounted on the end of the drum. 103, this gear being twice the diameter of the gear 107. The gear 107 mesheswith the gear 101* mounted together with the gear 101' on the driving shaft 101 and the gear 107 and gear 101" are equal in diameter. The driven shaft 102 carries the bowl 1080f the cream separator, which, together with other parts of said machine, being of well known cnstruction, I

need not be further referred to. A large bevel gear 101 is rigidly attached to the driving shaft 101 within the casing of the machine, and another bevel 'gear 101 of diameter equal therewith, is mounted on a I horizontal shaft 101?. and meshes with the bevel gear 101, so that wheii the-shaft 101 speed is required, and where such an increase with the use of forms of gearing I heretofore disclosed results in aruinous loss of energy, and requires the utmost exertion "for operation.
